Lyft has partnered with Taco Bell to debut a new feature that allows passengers to tack on a trip to the pseudo-Mexican fast food restaurant. The “Taco Mode” option is clearly an effort to woo late-night riders with the munchies, but some Lyft drivers are unsurprisingly disgusted by the thought of sloppy drunks defiling their backseats with nacho cheese and mystery beef.

Lyft’s head of marketing Melissa Waters told the New York Times that drivers will have the chance to opt in to Taco Mode. The company is pilot-testing the program from July 27 to 29 and August 3 to 6, in and around Newport Beach, California. Lyft plans to introduce the service in other cities over the next few months, and then expand it nationally in 2018.

According to the announcement, Taco Mode riders will get a free Doritos Locos Taco—a crunchy, messy treat that you should never eat in a car unless you truly hate the owner.

Update 7/26 7:00pm: A Lyft spokesperson shared the following statement:

At Lyft, we take great care to ensure any in-car activation or mode is a great experience for the passenger and driver. Taco Mode celebrates something many of our passengers and drivers are already doing together—stopping at the Taco Bell drive-thru on the way home.
